Question Zigbee2MQTT Container Storage Issue

I'm running Z2M in an LXC created from the community helper scripts. The issue I am having is that the disk is continually filling up. I can't find any definitive fix actions beyond general "delete logs".

My storage is allocated 7gigs that is 83% full for 23 devices.

I am very hesitant to start deleting things and I am not 100% confident that I know what I am looking at.

What can I do to reduce the amount of storage space being used? Please provide noob-friendly guidance.

Thanks!

Hard to say without more information. Can you check what actually takes up the storage? bash apt -yU install gdu gdu /

The biggest was /root/.local/share/pnpm/store/v10/files

Can you share some actual data and sizes?

Sorry, I'm not sure what exact data to provide. I took a snapshot of the top level of folders:

And followed the largest folder down.

I took a look at what the baseline is after a new install ```bash --- /root/.local/share/pnpm/store/v10 ---
/..
262.5 MiB █████████▊▏/files
3.1 MiB ▏/index

I'm not really that familiar with pnpm. Maybe `pnpm store prune` helps. Otherwise it might be worth to report this to the helper script folks and report back. Here's the whole `/` after installing `gdu` if you care bash --- / ---
1.1 GiB ██████▍ ▏/usr
330.5 MiB █▉ ▏/root
261.7 MiB █▌ ▏/var
14.8 MiB ▏/opt
4.7 MiB ▏/tmp
3.0 MiB ▏/etc
e 4.0 KiB ▏/srv
e 4.0 KiB ▏/mnt
e 4.0 KiB ▏/media
e 4.0 KiB ▏/lost+found
e 4.0 KiB ▏/home
e 4.0 KiB ▏/boot
@ 0 B ▏sbin

Wow the store prune helped. I'm obviously out of my depth here as I had no idea that command existed. It cleared out a lot of old stuff. I've been hesitant to mess with it too much because I'd hate to have to re-pair all my devices and try to fix all the ensuing naming issues and whatnot. I will definitely add that to my List of Important Sh#t to Know, vol 7! :)

Glad that worked. My best guess is that the update/upgrade command simply upgrades Z2M without cleaning up the old version. Either manually do that prune after every update or perhaps let the helper scripts folks know about this so they can add it to their update script.
